It's good, but it has two major flaws. The first is that it kind of sets you up thinking you are going to play a detective game, when in fact you are taking part in a thriller story with a detective investigation in it. You do get to do detectivy things (interviewing suspects, searching for clues etc), but the story will do what most Telltale games do and lead you down a single set of rails towards one major conclusion and one main culprit, whether you figure out the case yourself or don't.
It's other problem is that there is a bit of a mismatch between how the setting is supposed to work, and your role in the story. In the first scene, you (as the town sheriff) try to break up a fight. It goes south and the game prompts you to smash someone over the head with a huge axe - as a player, you might think this would count as a bit on the excessive side and refuse to do it, only to then receive an instant game over. If you do resort to police brutality, you discover that in this game, an axe through the brain isn't necessarily lethal at all. But then later still in the game, you see characters killed by comparatively trivial wounds. And also despite being a sheriff, you often get no option to arrest the people who keep trying to murder you, when logically that should be the first thing you would do once you've beaten them into submission.
I liked the characters and the thriller plot, but there is a lot of these incongruities that make it a little more confusing than it should be.
